I would be shocked if that were actually true. Maybe most top 10 programs do, but in general the variation in CS curricula is incredibly broad and includes tons of Java schools that only focus on imperative and OO paradigms with only passing mentions of functional programming in elective classes. I really have no idea if the data to support the claim even exists. One would probably have to manually comb through CS curricula to check. My suspicion is that it would not hold up.
